Rob Mazurek's Sao Paulo Underground and Black Cube SP bring some of the avant-iest jazz around to Will's Pub

You won’t find a more adventurous sonic explorer than Chicago-based Rob Mazurek (but lucky for us, we have the Civic Minded 5 to excitedly point him out). He’s a true tinkerer, incorporating computer programming and electronic keys to take his cornet places most jazz enthusiasts would never dream of traversing. His alternate universe of music is masterfully conjured by the players who comprise the cornet player’s electric jazz trio, São Paulo Underground, and his Black Cube SP, a frantic collision of São Paolo Underground with Brazilian rabeca fiddle player Thomas Rohrer; both perform this week in an almost out-of-place but decidedly cool engagement at cruddy Will’s Pub. With the bands’ influences ranging from early-’70s Miles Davis to Tortoise, it’s also a surreal invitation to time-travel and surrender to the group’s imaginative Brazilian folk-fueled whirl.
